Patented Sept. 8, 1931 UNITED STATES PATENT OFFICE FRANK MOSSBERG, 0F .ATTLEBORO, MASSACHUSETTS, ASSIGNOR '10 MOSSBERG PRESSED STEEL CORPORATION, OF ATTLEIBORO, MASSACHUSETTS, A CORPORATION OF MASSA- CHUSETTS Application filed May 21,

This invention relates to a warp beam of the type used for looms or weaving; and has for its object to provide a construction by which the warp ends may be fastened and tensioned by resilient means as the threads are wound upon the beam.

A further object of the invention is the provision of openings in the barrel of the warp beam with hook members within the barrel and yieldingly movably mounted relative thereto for tensioning the warp threads secured to the hooks.

A still further object of the invention is the provision of a strong and economical construction for mounting one of the heads at the end of a warp beam in a secure manner.

With these and other objects inview, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a sectional view taken through the barrel of the warp beam showing the tension hook member in position to have the warp threads secured thereto and showing in dotted lines the position of the hook as the threads are wound about the beam.

Figure 2 is a side elevation partly in section showing a plurality of hooks mounted within the beam.

Figure 3 is a sectional view of one of the hooks in the position which it assumes before I being pulled outwardly to have the warp threads secured thereto.

Figure 4 is a sectional detail of the mounting of the hook member within the barrel of the warp beam.

Figure 5 is a fragmental view showing a plurality of groups of warp threads secured to tension members before the warp threads are wound upon the beam.

In practice warp threads are manually secured to a warp beam by the operator and are generally not held in such a manner that they are equally tensioned throughout the width of the warp threads, thereby allowing slack in some of the threads, which is particularly detrimental in the weaving of silk or rayon warps; and in order to overcome this unde- WARP BEAM.

Serial No. 279,440.

sirable feature I have provided a plurality of openings in the barrel of the warp beam through which groups of threads may be resiliently tensioned by beingsecured' to movably mounted hook members tending to draw the threads through the openings; and the following is a detailed description of the present embodiment of this inventionshowing the preferred means by which these advantageous results may be accomplished:

Wit-h'reference to the drawings 10 designates one of the brackets which supports the warp beam in front of the warp machine and 11 the barrel of the beam which is provided witha plurality of spaced openings 12 along its length. Within the barrel 11 m in a position substantially in line with the openings 12; hook members 13 are pivotally mounted upon a suitable shaft 14 with a spring 15 tending to move the hook member into position illustrated in Figure 3. Shaft 14: is suitably mounted in spaced bearings 16 which in turn are supported on the plate 35, the whole being an assembly which may be readily positioned within the barrel and secured to the barrel as at 36.

Each ofthe hook members 13 is suitably shaped, as illustrated in Figure 3, so that upon swinging the hook upon its pivot the end portion 17 will pass through the opening 12 in the barrel and a detent18 formed on the backthereof will snap overthe edge of the opening into a recess 19 acent the opening 12 and be retained in the position shown in Figure 1. By the hook being held with its hook endportion 17 extending throughthe opening 12, it is in a convenient position to have the warp threads 20 manually tied there-about, as illustrated at 21 in Figure 1, it being understood that the width of the ,warp threads are dividedintoas many groups as there are attachinghooks along the length of the barrel so that the operator. may attach each group of threads 21 as illustrated in Figure 5 afterwhich each of the hooks is released by springing the same from engagementfrom the notch 19 to, allow the" threads to be partially drawn into the barrel through the opening as illustrated in dotted lines'in Figurefll so that the same may be properly tensioned before being wound upon the beam.

Each warp beam is provided at the ends thereof with an inner head 22 adjustably secured in position on the beam and an outer head 23 which is fixedly secured to the beam and consists of a main disk plate 24: having a flange 25 extending therefrom. This plate 24 is cut out as at 25 to receive the end of the barrel 11 and the head is also provided with an auxiliary plate 26 abutting the end of the barrel and welded to the plate 2 l as at 27 through which bolts 28 pass to hold the head to the web 29 suitably fastened within the barrel as at 30.

A second web 31 is secured as at 32 within the barrel at a point spaced from the web 29 and an axle 33 is supported in the two webs 29 and 31 and extends beyond the end of the head 23 for supporting the beam in the bracket 10. p In operating the warp beam, after the same is mounted in its bracket in front of the warp machine, each of the hook members 13 is drawn through an opening in the beam by a suitable tool-and held in the position illus trated in Figure 1 by the snapping of the detent 18 into the notch 19 in which position the warp threads are secured to the hooks after which the members are released from this outer position to allow the tension spring to act to tension the threads which is of particular advantage in warping silk and rayon threads to prevent slack of any of the threads throughout the width of thewarp.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In awarpbeam, a barrel about which the warp is wound having a plurality of openings spaced apart along the length thereof, a plurality of independently movable hooks pivotally mounted within said barrel to which the warp threads may be attached, each hook being located adjacent an opening, and independent springs acting upon said hooks to move them relative to said barrel to independently tension the threads.

2. In a warp beam, a barrel about which the warp is wound having an opening therethrough, a member to which warp threads may be attached pivotally mounted in said barrel to swing throughsaid opening, resilient means tending to move said member to a position within said barrel, said memberbeing shaped to catch over the edge of said opening to hold the same against the action of said resilient means for convenience in attaching the threads thereto.

3. In a warp beam, a barrel about which the warp is wound having an opening there- FRANK MOSSBERG.
